But a problem popped up. The axle kept tipping off the little nub. It wouldn't seat correctly.
Here is the culprit. The bolt holding together extended too far. This stock location is _under_ the spring, not above it. One of the cubbie mods is to place the axle over the springs - which I was I cut that notch above.
So in the standard layout that bit of thread and bolt shouldn't make contact with the axle.
